This is the second part to Hoshi mamoru inu. Second instalment is twisted with main and side characters of first installment with extra additional main characters.
As the title says, story revolves around Dogs. Story in this part is indirectly linked to the first one. Mangaka has drawn some quality drawings with great detail and in a way enjoyable.
Storyline is about regret and forgiveness and interstate change of mind among characters. I am amazed that mangaka did such development with in a short period of chapters. It's actually brilliance of the author.
Last but not least the lesson from the book, " Dogs are always loyal, they will always be there for you".
Overall great manga for sad-happy rollercoaster.
